TITLE

plural NETGEAR Out-of-bounds write vulnerabilities in devices

Trust: 0.8

sources: JVNDB: JVNDB-2017-014934

DESCRIPTION

Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D7800 before 1.0.1.28, R6100 before 1.0.1.16, R7500 before 1.0.0.112, R7500v2 before 1.0.3.20, R7800 before 1.0.2.36, R9000 before 1.0.2.52, WNDR3700v4 before 1.0.2.88, WNDR4300 before 1.0.2.90, WNDR4300v2 before 1.0.0.48, and WNDR4500v3 before 1.0.0.48. plural NETGEAR The device is vulnerable to out-of-bounds writes.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. NETGEAR D7800, etc. are all products of NETGEAR. NETGEAR D7800 is a wireless modem. NETGEAR R7500 is a wireless router. NETGEAR WNDR3700 is a wireless router. The vulnerability stems from the fact that when the network system or product performs operations on the memory, the data boundary is not correctly verified, resulting in incorrect read and write operations to other associated memory locations. Attackers can use this vulnerability to cause buffer overflow or heap overflow
